“I want to meet him,” said Marian. “Will you please come with me to his tent?”

A moment later a hearty old man came to the door of the tent in response to their call, and with a cheery smile acknowledged the Major’s introduction of Marian and Patsy, at once inviting them in.

Imagine Marian’s surprise, when upon entering the tent she saw a young girl of about her own age, seated at a radio sending set. And there, under the deft fingers of the girl operator, a crackling purple flash jumped back and forth across a wide spark gap.

“The girl of the purple flame,” gasped Patsy.

At sound of her voice the girl turned around and smiled a welcome. Marian turned to Mr. Montgomery:

“So you are the people of the purple flame.”

“Are we, indeed!” laughed the old Prospector.

“Yes,” said Marian, “and I thought all the while, back there in Alaska, that you were dogging our footsteps, and, to speak honestly, we feared you.”

“Well, well,” laughed the old gentleman. “So that was your reindeer camp. We thought all the while that you were dogging our footsteps.”

Then the old prospector launched into a long story that cleared up the entire mystery of the purple flame.
